glsl: Enable GLSL ES 3.00 features inherited from desktop GLSL.

This patch turns on the following features for GLSL ES 3.00:

- Array constructors, whole array assignment, and array comparisons.
- Second and third operands of ?: may be arrays.
- Use of "in" and "out" qualifiers on globals.
- Bitwise and modulus operators.
- Integral vertex shader inputs.
- Range-checking of literal integers.
- array.length method.
- Function calls may be constant expressions.
- Integral varyings must be qualified with "flat".
- Interpolation and centroid qualifiers may not be applied to vertex
  shader inputs.
